NOP Rule:
205.601(j)(6)(ii) Micronutrients—not to be used as a defoliant, herbicide, or desiccant. Those made from nitrates or chlorides are not allowed. Soil deficiency must be documented by testing. (ii) sulfates, carbonates, oxides, or silicates of zinc, copper, iron, manganese, molybdenum, selenium, and cobalt.

Micronutrients – synthetic

Status:
Allowed with Restrictions

Class:
Crop Fertilizers and Soil Amendments

Origin:
Synthetic

Description:

Use restricted to cases where soil/plant nutrient deficiency is documented by soil or tissue testing. Micronutrients include: boron, cobalt, copper, iron, manganese, molybdenum, selenium, and zinc. Carriers, fillers, chelating agents, and complexing agents must either be nonsynthetic, or must be on the list of allowed synthetics. See other MICRONUTRIENTS – SYNTHETIC listings, and TRACE MINERALS – NONSYNTHETIC.

NOP Rule:
205.601(j)(6) As plant or soil amendments… Micronutrients—not to be used as a defoliant, herbicide, or desiccant. Those made from nitrates or chlorides are not allowed. Soil deficiency must be documented by testing.
(i) Soluble boron products
(ii) Sulfates, carbonates, oxides, or silicates of zinc, copper, iron, manganese, molybdenum, selenium, and cobalt.

Zinc Products

Status:
Allowed with Restrictions

Class:
Crop Fertilizers and Soil Amendments

Origin:
Synthetic

Description:

Zinc carbonate, zinc oxide, zinc silicate, and zinc sulfate may be used to correct a documented zinc deficiency. See also MICRONUTRIENTS – SYNTHETIC listings.
